DDR3 Registered DIMM
DDR3 Registered DIMM is high-speed, low power memory module that
use DDR3 SDRAM in FBGA package, 1 pcs register in TFBGA package
and a 2048 bits serial EEPROM on a 240-pin printed circuit board. DDR3
Registered DIMM is a Dual In-Line Memory Module and is intended for
mounting into 240-pin edge connector sockets.
Synchronous design allows precise cycle control with the use of system
clock. Data I/O transactions are possible on both edges of DQS. Range
of operation frequencies, programmable latencies allow the same device
to be useful for a variety of high bandwidth, high performance memory
system applications.
